took a bit of muscle putting it together, as some of the rods had a bit too much chrome on them, making it hard to screw together . I had to use a vise-grip and a wrench.
but this is no doubt my first and only prop balancer I will ever buy. super solid and well built.
imagine if any balancer can do boats, this is is. (RC boats that is). they have some demo's on their website. (which isn't loading very well right now http://www.hobby.dubro.com)
I use the Top Flight magnetic balancer, works great and only $20. Another nice thing about this one is it all packs up into the side uprights, they become a case for all the parts to it.
